Application filed June 5J This' invention relates Ato cooking ranges and more especially to a stove for cooking the prepared meat batch employed in the manufacture of Hamburger sandwiches now generally sold at amusement. and beach yresorts, and at lunch and sandwich stands established along highways.

It is an objectof the present invention to 'facilitate 'the `cooking' of the Hamburger meat batchesV and to maintainin a hotl condition the vcooked batch ready for instant service on demand.

A further purpose is tofprovide a stove of this character in which there is a cooking pan having upright. walls surrounded by a casing forminga narrow hot air chamber for the intimate passageof hot air from burners to the side walls of the stove pan so that the latter are efficiently heated with an economy `of gas consumption.

An additional object is to provide a stove of this character with a front making-up shelf and a plurality of lids-or covers which may be severally raised or left lowered to serve as warming plates for made-up sandrate closed chamber at either the cookingA end or the hot plate end of the stove.

A further object is to provide a cooking stove which-is of few and simple parts all of which are readily accessible for adjust-` ment and cleaning so as tobe kept in a thoroughly sanitary condition.

Other objects, advantages and features of construction and combination, and details of means will be made manifest in the ensuing description of the herewith illustrative einbodiment; it being understood that modifications, variations and adaptations maybe resorted to within the spirit, scope and principle of the invention as it is more directly claimed hereinafter.

In itsillustrated Vfori-n the stove includes y a front panel 2 anda rear panel 3 and end panels l constituting an outer casing around f an inner cooking panshown here as' having.-

a flat bott-oni' having a longitudinal incli-v nation from end to end of the stove. The Lbottom is provided with front and rearA walls 6-7 and end walls 8 all of which arespaced inwardly from the outer'casing so as to'- form Y rather narrow hot air spaces beneath amarginal top 'frame 9. j i y l The casing structure extends considerably below the lowest point of the cooking pan and is preferably supported on elevating coi'-` ner legs l0 here shownas in the form of Y,

angle iron members secured iii overlapping position on the corners of the casing. The

elevation Aof the casing allows fresh air to pass upwardly to burners l1 of which v`a series is connected to a supply pipe l2; each burner havingits own valve 13 to regulate heat under the adjacent portion of the ini clined bottom 5 of the pan. For convenience of access a front panel 2 is provided with a series of liand-lioles 14.- adjacent to the valves 13 and being covered by movable closures 15. y

For economy of yfuel it is desirable 'to coni duct the hot gases upwardly along the sides and ends of the'cooking 'pan so that this is eiliciently heated not only on the bottom but on its sides and ends as well. yThis effect is obtained by formingthe hot air chambers around the pan walls. Circulation is obtained and vestablished by providing` small outlet vent holes 16 in the end and rear panels of the stove casing.

On the top of the stove there is hingedly mounted a set of plane covers 17` adapted to be lowered onto the top frame 9. Thus either of the covers can be lifted for access to the pan without disturbing the other and the covers can be utilized as hot plates for prepared Hamburger sandwiches.

To increase facility of the stove there is provided along the front thereof a shelf 18l useful to receive batches of uncooked meat and also serving as a table for the makingup of the sandwiches.

An important lfeature of the present invention is to provide means for drawing or dragging the cooked batch of meat from one end of the stove to the other end where itv is maintained in i'eserve and in convenient i position for access during the making of lmounted in brackets 22. These brackets are designed to be shifted along the top of the pan vfrom position to position and frictionally held at selected positions to support the transverse partition at the desired-location. l 'y The bracket is shown as having outwardly deflected shoe ends 23 springing frictionally against the side walls of the pan and .also vhave out-turned ledges 24 slidably bearing and shiftable on the inner corners of the 'pan frame 9. The end heads of the pivot 21 which carries the partition 2O clinch over the brackets 2l but are clear of thel walls of the pan. The upper part of the partition 20 is provided with a hand-hole 25 for convenience of adjustment.

The lower or right hand end of the stove pan is utilized for the'cooking portion and in operation after a batch oi meathas been cooked to the desired degree the partition 2O is shifted over to the end wall at the lower end and the cooked batch is then drawn up, using the partition as a scraper, to the upper end of the pan which is maintained at a suitable degree of temperature to keep the cooked batch hot. It will be seen that the partition will serve to separate the cooked from the uncooked batch and either of the lids 17 may be lowered to keep the heat in either end at which the partition may be adjusted.

What is claimed is:

1. 'A stove for cooking Hamburger sandwich meats comprising an interior pan having an inclined bottom, and an adjustable ,i

ing an inclined bottom, andan adjustableV transverse partition forming a scoop whereby to scrape thebatch from the lower cooking end upward to the upper hotspot end; said partition being pivoted on a sliding carrier; said carrier including friction brackets engaging side walls of the pan.

il. A stove for cooking Hamburger sandwich meats comprising an interior pan having an inclined bottom, and an adjustable transverse partition forming a scoop whereby to scrape the batch from the lower cookmg end upward to the upper hot-spot end; said partition being pivoted on a sliding carrier; said carrier including friction brackets engaging side walls of the pan and havin g riding ledges resting on the pan rim.

5. In combination, a Hamburger sandwich meat cooking stove having a pan, and a detachable partition having sliding brackets resting on and adjustable along the rim'of the pan; said partition forming a scoop to draw along the cooked meat and to divide the cooked and uncooked batches.

6. A stove, for cooking Hamburger meat batches, including a pan having upright side and end walls and a flat bottom, and a movable partition fitting the side walls and dragging on the bottom, whereby to draw the cooked meat from the cooking end of the pan.
